Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a method of constructing a curtain wall.

[Conventional technology]

Conventional curtain wall construction methods include, for example, fixing mullions to the building frame in advance;
One method was to attach a horizontal frame to this to form a wall frame, and then attach panels such as glass or decorative laminate to this frame.

In other words, this construction involved the following steps.

First, as shown in FIG. 8A, a plurality of mullions 2 are fixed to the beam 1, which is the frame, via brackets. At that time, they are positioned in the internal and external directions, the frontage direction, and the vertical direction, and are fixed at regular intervals.
Then, like simultaneous b, place horizontal frame 3 between each mullion 2.
are sequentially attached at regular intervals using screws or the like via brackets to create a wall frame consisting of the mullion 2 and the horizontal frame 3 as shown in FIG. After that, panel 4 of glass, decorative board, etc. is attached to this frame.
Attach it via a press edge, etc.

FIG. 9 shows a curtain wall obtained by such a construction method.

[Problem that the invention seeks to solve]

However, this construction method had the following problems.

(1) Since the mullions 2 are attached in advance to the beam 1, which is the frame, at a certain interval, it is difficult to accurately determine the relative positional relationship of each mullion 2, and it is difficult to accurately position them. It required time and skill, and construction efficiency was poor.

(2) Also, since the structure is such that the horizontal frame 3 is attached with screws etc. through brackets between the multiple mullions 2 which are fixed in advance to the beam 1 which is the frame, the mullions 2 and the horizontal frame 3 A certain amount of clearance had to be provided between the two, and inevitably a gap was created between it and the mullion 2. As a result, not only the screws for mounting but also the bracket became visible from the outside, resulting in an unsightly appearance.

(3) Of course, if you make a notch in the horizontal frame in advance and fit it into the mullion bracket from this part to prevent it from coming out, you can avoid using screws, but you will need to make the notch. However, since the notch in the horizontal frame is visible from the outside, the problem of appearance still cannot be solved.

This invention was made to solve these conventional problems, and its purpose is to provide a structure in which a mullion is followed by a horizontal frame, and a horizontal frame is followed by a mullion. In particular, (1) accurate positioning of the mullion is easy and construction efficiency is good; (2) moreover, there is no gap between the mullion and the horizontal frame, so it fits well; To provide a method of constructing a curtain wall that can obtain a curtain wall with good appearance.

(3) Connect the mullions in the second row in the length direction with a connecting member, fit the horizontal frame fitting protrusion into the other end of the first horizontal frame, and connect the side surfaces of the mullions in the second row to the second row. By making it contact the other end surface of the horizontal frame 1, determining the position of the mullions in the inside/outside direction and the vertical direction in this state, and fixing the mullions in the second row to the building frame with brackets, The third step is to attach the second row of mullions.

(4) A fourth step of repeating the second and third steps to sequentially attach the second horizontal frame to the second row of mullions, and the third row of mullions to the second horizontal frame.

(5) A fifth step in which panels such as glass and decorative boards are attached to the wall frame consisting of the mullions and horizontal frames obtained in the first to fourth steps.

Further, in the curtain wall construction method according to the present invention, in the third step, bolts and nuts are inserted into the first horizontal frame and the mullion bolt holes, and the first horizontal frame, the first row, and the A process for integrally tightening the second row direction is provided as necessary.
